| # Persian OCR Double Benchmark |
|
|
| A frozen, leakage-controlled Persian OCR benchmark with two equally weighted splits: |
|
|
| - `printed`: **6,669** rows carved from `Reza2kn/persian-printed-ocr-3.5m` at `ba02f36c3d496838d8fad9aff352b77763af1ea4`. |
| - `handwriting`: **6,669** rows carved from `Reza2kn/persian-handwriting-pages-3.69m` at `b114f0a36a6a2e397bc93517dd084431bfca2329`. |
|
|
| The exact rows were uploaded here before being removed from their source training repositories. |
| Each row retains its original repository, revision, Parquet shard, row index, image SHA-256, and |
| deterministic selection hash. Selection uses seed **6,669** over multiple deterministic candidate |
| shards, followed by stable content-hash ordering. |
|
|
| ## Metrics |
|
|
| Models are scored separately on each split with corpus-level Persian-normalized WER and CER, |
| ShenavaSanj S³, and essential-word error. S³ is the sum of ShenavaSanj importance for substituted |
| or deleted reference words divided by total reference importance. Essential words have importance |
| at least 0.8. The Triple Threat score is the mean of WER, CER, and S³; the combined leaderboard |
| uses an equal 50/50 macro-average across the two splits. Lower is better. |
